Why is the fan switch only working on 3 and 4 and not on 1 and 2?

I suspect that 1 & 2 have a different relay than 3 & 4. The relay is likely under the hood, on the firewall. check blower motor resister!!

What would be the cause of your heat only working sometimes in your Hyundai Elantra when you can hear the switch clicking when you turn it?
Possibly a fan resistor. Does it work on only certain speeds like 1 and 2 but not 3 and 4?
I have a 2000 Nissan sentra. My blower fan switch is numbered 1 to 4 and when i turn it on it only works on number 4.?
Blower resistor switch
2004 trailblazer fan switch not working is it the switch or blower motor resistor the switch did not go out all at once it worked on 1-3 for a while then went totally out?
If the resistor was bad you would still have high speed. If you have no speeds I would suspect the switch and/or pigtail plug at the switch.
Why does a fan only work on high?
More information would be needed to diagnose your problem more accurately, but here are some tips to start: 1) Fans will not work with dimmers. If you have a dimmer controlling your fan, it will only work when the dimmer in is the full intensity position (if at all). You will need to replace the dimmer with a fan speed control. If one switch controls both the fan and the light, this will not solve your problem, as a light will not work with a fan speed control switch. You will have to settle with a standard single pole switch, a remote switch, or get one more wire between the switch and the fan. 2) If you have a fan speed control switch, but the fan doesn't seem to respond as it should, you may want to pull on the pullchain directly on the fan. If the pullchain is not set to high, your speed control will not work correctly. 3) If #2 or #3 don't apply to you, and you are simply using the pull chain on the fan, you may have a bad switch inside the fan housing, loose or disconnected wires to the fan (unlikely), or simply a bad fan motor.
The blower of your Focus works only at high speed Also AC does turn on What could be happening?
(1) Faulty fan switch -OR- (2) the resistor on the circulating fan has gone bad.
What would cause the heater fan to work only in the number 4 and 5 positions but not the number 1 to 3 positions in a 2002 Trailblazer?
either the switch is fallty or one of the fan coil is brocken or rusty , if you want to varefy ,, unplug the switch and test it with multimeter
Heater fan switch not working on 1 and 2 setting on 2000 Pontiac Montana?
I just had that same problem..I took it in to have it fixed and they replaced the blower motor resistor and that seems to have fixed the problem
Home air condition is blowing air only?
1. Is the fan and compressor on the outside (codensor unit) working? A. Thermostat switch off, set to fan only. B. Check the circuit breakers or fuses. There may also be a fuse box near the compressor. C. The control wire to the compressor is cut or broken. D. Low freon. E. Burnt out compressor. F.Capacitor( run or start)or both is bad
2002 Accord Fan switch only works in the 3 and 4 position 1 and 2 won't work at all Help?
Could be a bad switch, but it is more than likely a bad blower motor resistor pack.
Im adding a new ceiling fan in my living room i pulled the old fixture down i noticed 2 sets of 3 wire BWR and 1 set 2 wire BW BW going to the wall switch how should you wire in the fan?
White is for neutral on the fan, black is power for the motor, and red is power for the light. If the power from the switch only has two wires (black and white), you would hook up white to white and hook black and red from the fan to the black wire from the wall switch. This means that you'll be powering the fan and light on the same switch and to change the fan and light separately you will have to pull on the chains or use a remote control.
